Heartburn is caused by acid from your stomach backing up into your esophagus.
But what causes that acid to back up?
Certain foods cause your body to produce more acid, while other foods cause your lower esophageal sphincter (aka the LES) to relax, letting more acid escape into your esophagus. This is why some foods cause you more discomfort.
Some Foods That Can Cause Heartburn
- Chili peppers and other spices
- Garlic and onions
- Fried foods
- Avocados, nuts, and cheese
- Citrus fruits and juices
- Tomato-based foods, like spaghetti sauce, salsa, chili, and pizza
